Camels: Facts, Types & Pictures | Live Science Lacking a protected fluid-filled cavity requires the non-amniotic eggs of amphibians to remain in water. The amniotic egg allowed tetrapods to become completely terrestrial. All amniotes have three membranes surrounding the fetus of one offspring. Filling up on water, when it's available, is very important for camels. However, placental mammals also have fewer offspring compared to sauropsid amniotes. Female camels have a gestation period of 12 to 14 months. Biology 101 Chapter 11 Flashcards | Quizlet Like most mammals, camels give birth to a live young.
